When you have a quantitative variable, it can be discrete or continuous. In broad terms, the difference between the two is the following: You count discrete data. You measure continuous data. Discrete variables can only take on specific values that you cannot subdivide. Frequently, discrete data...
Dichotomous are the simplest possible variables.The point here is that -given the sample size- thefrequency distributionof a dichotomous variable can be exactly described with a single number: if we've 100 observations on sex and 45% is male, then we know all there is to know about this va...
in computing, a variable is a piece of memory that stores a value that can be changed. a variable can refer to anything from numbers and strings to objects, collections, and pointers. variables are essential in software programs—without them, most modern computing functions would be impossible...
A variable might stand for a range of numbers that can be used in a mathematical expression; a variable might be used in a universal statement that is true for all numbers; or a variable might stand for a specific value such as the solution to an equation or word problem. ...
In science, when a variable is studied, itsattributeis recorded. A variable is a characteristic, while an attribute is its state. For example, if eye color is the variable, its attribute might be green, brown, or blue. If height is the variable, its attribute might be 5 m, 2.5 cm, ...
